Energy Secretary Steven Chu is claiming that scientific evidence for climate change is as convincing as ever — a comment that arrives just as controversies surrounding the renewable energy industry and new Environmental Protection Agency (EPA) rules face staunch opposition from Republicans and industry groups.

Energy Secretary Steven Chu is claiming that scientific evidence for climate change is as convincing as ever — a comment that arrives just as controversies surrounding the renewable energy industry and new Environmental Protection Agency (EPA) rules face staunch opposition from Republicans and industry groups.

"Over the last couple of years, the dispassionate, hard science evidence has been mounting, increasing," Chu claimed at an energy forum sponsored by the New York Times. The Energy Secretary acknowledged that "we don’t understand everything," but that evolving weather patterns and other climate-related factors are leading to a sea level rise.

Chu contended that the vast majority of scientists believe global warming is a serious problem, and that countless studies show that environmental destruction is already running its course on the earth. One common assertion, for instance, is that warming trends are wiping out the polar bears in the Arctic and northern Canada. But as has been the case with other popular arguments coming from global warming alarmists, there have been countless studies that have refuted these catastrophic doomsayer scenarios. For example, a survey released earlier this month seemed to prove the polar bear argument false:

The debate about climate change and its impact on polar bears has intensified with the release of a survey that shows the bear population in a key part of northern Canada is far larger than many scientists thought, and might be growing.

The number of bears along the western shore of Hudson Bay, believed to be among the most threatened bear subpopulations, stands at 1,013 and could be even higher, according to the results of an aerial survey released Wednesday by the Government of Nunavut. That’s 66 per cent higher than estimates by other researchers who forecasted the numbers would fall to as low as 610 because of warming temperatures that melt ice faster and ruin bears’ ability to hunt. The Hudson Bay region, which straddles Nunavut and Manitoba, is critical because it’s considered a bellwether for how polar bears are doing elsewhere in the Arctic.
